Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513804, here are decompositions:

23 + 513781 = 513804
37 + 513767 = 513804
43 + 513761 = 513804
73 + 513731 = 513804
107 + 513697 = 513804
113 + 513691 = 513804
131 + 513673 = 513804
163 + 513641 = 513804

Showing the first eight; more decompositions exist.
